X11: TTY-style status lines

Set X resource NetHack*fancy_status: False to enable the TTY-style
status lines. Default is the fancy status.

This patch is somewhat unfinished - even though the TTY-style status
allow for status hilites, the colors don't work correctly yet.
Also changes the fancy status to use the windowport notification code.
